Question

Consider eight, eight-cubic centimeter (8 cm3) sugar cubes stacked so that they form a single 2 x 2 x 2 cube. How does the surface area of the single, large cube compare to the total surface area of the individual eight cubes

Answer 1

The edge if each cube is of 2cm. therefore the surface area of each small cube is \[24 cm^2\] However, since there is 2*2*2 cube made with eight small cubes, the edge of the bigger cube now becomes 4cm. thus the surface area of the bigger cube is \[96 cm^2\]
